System and method for biometric authentication using social network

ABSTRACT

Techniques described herein include systems and methods for biometric authentication utilizing a dynamically updated biometric template derived from social media content of a user. In some embodiments, a service provider computer receives an authentication request that comprises biometric data provided by the user utilizing a user device. Social media content associated with the user may be received by the service provider computer from a social network service computer. In embodiments, the service provider computer may generate a biometric template for the user based on the received social media content where the biometric template is continually updated based on new social media content shared by the user. The service provider computer may determine a confidence score based on a comparison of the biometric data and the biometric template. The service provider computer may verify the authentication request for the user based at least in part on the confidence score.

BACKGROUND

Identity fraud in the consumer transaction service industry is a problem. For example, many consumers can complete a transaction using a consumer device (e.g., a mobile phone or laptop computer) without visiting a brick-and-mortar merchant or presenting a physical payment card. In some examples, a user can initiate a payment transaction from the consumer device at a point-of-sale-terminal, in a remote payment environment, or online via e-commerce web pages. Some consumer device initiated transactions may require biometric authentication to verify the identity of the user. Some previously implemented systems attempt to decrease fraud in these transactions by utilizing biometric authentication that uses a stored static biometric template. For example, a static biometric template (e.g., based on a fingerprint) can be stored on the user device and compared for matching to recently submitted biometric data making it harder for fraudsters to compromise the identity verification. However, such methods for biometric authentication may utilize a non-revocable biometric template that fails to adjust or update based on the age or activity of the user that a service is attempting to authenticate. As such, a fraudster can obtain a sample of the biometric data (e.g., fingerprint) and fraudulently identify as the user in a process that compares the biometric data to a static or non-revocable biometric template. Moreover, systems that store the biometric template on a payment transaction server or merchant computer may be prone to compromise thus destroying any protection granted by requiring biometric authentication.

Embodiments of the invention address these and other problems individually and collectively.

BRIEF SUMMARY

In some embodiments of the invention, systems and methods for biometric authentication are provided. The biometric authentication system can utilize a biometric template that is generated based at least in part on social media content shared by or associated with a user from a social media network provider. Systems can strengthen the established identity of the user by utilizing a revocable biometric for generating the biometric template that reflects changes in the user due to age or activity. In some embodiments, biometric data provided by a user during authentication can be matched with the dynamic biometric template to verify the identity of the user. The dynamic biometric template can be generated and stored on the user device, on a social media network provider's server, or a service provider computer. In some embodiments, the comparison or determination of a confidence score that represents a match between biometric data provided by a user during authentication and the dynamic biometric template can be performed on the user device, on the social media network provider's server, or the service provider computer. The confidence score may be compared to a threshold to determine that the user's identity is verified or authenticated.

Some embodiments of the invention are directed to a method for biometric authentication including receiving, by a server computer and from an access device, an authentication request that comprises biometric data provided by a user. The method may further include transmitting, by the server computer, the biometric data to a social network server computer. The social network server computer may thereafter compare the biometric data of the user to a biometric template to calculate a confidence score. In some embodiments, the biometric template may be generated based at least in part on social media content shared by the user on a Web Site provided by the social network server computer. The method may also include receiving, by the server computer, the confidence score from the social network server computer and verifying the authentication request based at least in part on the confidence score.

In some embodiments, the method may also include creating a fraud score based at least in part on the confidence score and a threshold and updating a fraud database using the fraud score. The fraud database may be maintained by the server computer.

In some embodiments, the authentication request is in the form of an authorization request message that requests authorization for a payment transaction, wherein the method further includes transmitting, by the server computer, an authorization response message to the access device.

In some embodiments, the method may further comprise determining, by the server computer, a threshold for the payment transaction based at least in part on transaction information provided by a merchant associated with the payment transaction. In some embodiments, the threshold is updated based at least in part on the social media content shared by the user.

In some embodiments, the method may also include calculating the confidence score based at least in part on information indicating a level of activity of the user with the Web Site provided by the social network server computer.

In some embodiments, the social media content shared by the user on the Web Site includes at least one of video content, audio content, image content, text content, user provided input, or user provided activity with the Web Site.

In some embodiments, the biometric data is provided by the user via a user device. In some embodiments, the method may also include that the biometric template is dynamically updated based on new social media content shared by the user on the Web Site provided by the social network server computer.

Some embodiments of the invention are directed to a method for biometric authentication including receiving, at a server computer and from an access device, an authentication request for a user associated with the access device where the authentication request comprises biometric data provided by the user. The method may further include receiving, by the server computer and from a social network service computer, social media content associated with the user. The method may also include generating, by the server computer, a biometric template for the user based at least in part on the social media content. In some embodiments, the biometric template may be continually updated based at least in part on new social media content associated with the user. The method may include determining, by the server computer, a confidence score based at least in part on the biometric data and the biometric template and verifying the authentication request for the user based at least in part on the confidence score.

In some embodiments, the method may further include selecting, by the server computer, a threshold from one or more thresholds to verify the authentication request based at least in part on information identifying characteristics of the authentication request.

In some embodiments, the biometric template is updated at periodic intervals.

Other embodiments of the invention are directed to servers and systems that are configured to perform the above-described methods.

These and other embodiments of the invention are described in further detail below.

DETAILED DESCRIPTION

Prior to discussing embodiments of the invention descriptions of some terms may be helpful in understanding embodiments of the invention.

A “payment device” may include any suitable device capable of making a payment. For example, a payment device can include a card including a credit card, debit card, charge card, gift card, or any combination thereof. A payment device can be used in conjunction with a consumer device, user device, or user computer device as further defined below.

A “payment processing network” (e.g., VisaNet™) may include data processing subsystems, networks, and operations used to support and deliver authorization services, exception file services, and clearing and settlement services. An exemplary payment processing network may include VisaNet™. Payment processing networks such as VisaNet™ are able to process credit card transactions, debit card transactions, and other types of commercial transactions. VisaNet™ in particular, includes a VIP system (Visa Integrated Payments system) which processes authorization requests and a Base II system which performs clearing and settlement services.

An “authorization request message” may be an electronic message that is sent to an authorization system such as a payment processing network and/or an issuer computer to request authorization for a transaction. An authorization request message is an example of a transaction message. An authorization request message according to some embodiments may comply with ISO 8583, which is a standard for systems that exchange electronic transaction information associated with a payment made by a consumer using a payment device or a payment account. The authorization request message may comprise a primary account number (PAN), expiration date, service code, CVV and other data from a payment device. In some embodiments of the invention, an authorization request message may include a payment token (e.g., a substitute or pseudo account number), an expiration date, a token presentment mode, a token requestor identifier, an application cryptogram, and an assurance level data. The payment token may include a payment token issuer identifier that may be a substitute for a real issuer identifier for an issuer. For example, the real issuer identifier may be part of a BIN range associated with the issuer. An authorization request message may also comprise additional data elements including, by way of example only: a service code, a CVV (card verification value), a dCVV (dynamic card verification value), an expiration date, etc.

An “authorization response message” may be an electronic message reply to an authorization request message generated by the authorization system. The authorization response message may include an authorization code, which may be a code that the authorization system returns in response to receiving an authorization request message (either directly or through the payment processing network). The authorization response message is received at the merchant's access device (e.g. POS terminal) and can indicate approval or disapproval of the transaction by the authorization system.

A “server computer” may be a powerful computer or cluster of computers. For example, the server computer can be a large mainframe, a minicomputer cluster, or a group of servers functioning as a unit. The server computer may be associated with an entity such as a payment processing network, a wallet provider, a merchant, an authentication cloud, an acquirer or an issuer. A user device computer, social network provider computer, or service provider computer may all be examples of server computers.

An “access device” can include a device that allows for communication with a remote computer, and can include a device that enables a customer to make a payment to a merchant in exchange for goods or services. An access device can include hardware, software, or a combination thereof. Examples of access devices include point-of-sale (POS) terminals, mobile phones, tablet computers, laptop or desktop computers, user device computers, user devices, etc.

“Biometric data” includes data that can be used to uniquely identify an individual based upon one or more intrinsic physical or behavioral traits. For example, biometric data may include retinal scan and tracking data (i.e., eye movement and tracking where a user's eyes are focused). Further examples of biometric data include digital photographic data (e.g., facial recognition data), digital sound data (e.g., voice recognition data), deoxyribonucleic acid (DNA) data, palm print data, hand geometry data, and iris recognition data.

A “biometric template” can be a digital reference of characteristics that have been extracted from one or more biometric samples. In some embodiments, the biometric samples may be derived from social media content shared by or associated with a user. In some embodiments, a biometric template may be derived from biometric data. A biometric template as used herein includes biometric templates for revocable and non-revocable features associated with a user such as facial images and voice samples. Examples of non-revocable features associated with a user include a fingerprint. Biometric templates are used during the biometric authentication process. Data from a biometric sample provided by a user at the time of authentication can be compared against the biometric template to determine whether the provided biometric sample closely matches the biometric template.

A “resource providing entity” can be any entity that provides resources during a transaction. For example, a resource providing entity can be a merchant, a venue operator, a building owner, a governmental entity, etc.

An “authentication request” includes a request to authenticate a person or circumstance. The authentication request may be an electronic message that is sent to a service provider computer or an authorization system such as a payment processing network and/or an issuer computer to request verification of a user identity. In some embodiments, an authorization request can be an example of an authorization request message that is an example of a transaction message. The authorization request may comprise biometric data provided by a user for verification of the user's identity before a transaction or authentication request message is generated. In some embodiments, the authentication request includes access device or user computer device identification information, user location information, network access information, or an application request. As described herein, a user's identity may be verified upon receiving an authentication request by comparing submitted biometric data to a biometric template that is generated using social media content that is shared by or associated with the user.

“Social media content” includes any suitable activity shared or provided by a user in conjunction with a social media service that is provided or hosted by a social media provider. For example, social media content may include any images, video, text, audio, user activity, links, or upload activity by a user utilizing a Web Site or software application that is provided by a social media provider. Further, social media content may include suitable content shared or provided by the user with a social media service including video content, audio content, image content, text content, user provided input, or user provided activity with an associated Web Site or application of a social media service. In some embodiments, social media content may be associated with or provided by the user utilizing an application provided by the social media provider. Examples of social media providers include FACEBOOK, INSTAGRAM, TWITTER, SNAPCHAT, ETSY, MYSPACE, GOOGLE PLUS, or any suitable social media outlet.

A “confidence score” can include a value or metric that represents trust in a particular situation. For example, a confidence score may relate to the degree of similarity between biometric data provided by the user and a dynamic biometric template derived from social media content. In some embodiments, the confidence score represents how closely the biometric data matches the biometric template. In some embodiments, the confidence score can be compared to one or more thresholds maintained by a service provider or payment processing network to determine whether the user identity is verified as part of a payment transaction process. In embodiments, the confidence score can be modified based on information that indicates a level of activity of a corresponding user with their associated social media networks. For example, the confidence score may be weighted greater if a user is active and provides a large amount of data to a social media source whereas a user who is less active and does not share much information via associated social media networks may be weighted differently.

A “user device” may be any type of computing device such as, but not limited to, a mobile phone, a smart phone, a personal digital assistant (PDA), a laptop computer, a desktop computer, a server computer, a thin-client device, a tablet PC, a vehicle such as an automobile, etc. Additionally, user devices may be any type of wearable technology device, such as a watch, earpiece, glasses, etc. A user device may include one or more processors capable of processing user input. The user device may also include one or more input sensors for receiving user input. As is known in the art, there are a variety of input sensors capable of detecting user input, such as accelerometers, cameras, microphones, etc. The user input obtained by the input sensors may be from a variety of data input types, including, but not limited to, audio data, visual data, or biometric data. The user device may comprise any electronic device that may be operated by a user, which may also provide remote communication capabilities to a network. Examples of remote communication capabilities include using a mobile phone (wireless) network, wireless data network (e.g., 3G, 4G or similar networks), WI-FI, Wi-Max, or any other communication medium that may provide access to a network such as the Internet or a private network.

In the following description, various embodiments will be described. For purposes of explanation, specific configurations and details are set forth in order to provide a thorough understanding of the embodiments. However, it will also be apparent to one skilled in the art that the embodiments may be practiced without the specific details. Furthermore, well-known features may be omitted or simplified in order not to obscure the embodiment being described.

Techniques described herein include a system and platform for biometric authentication. The biometric authentication system can utilize a biometric template that is generated based at least in part on social media content shared by or associated with a user from a social media network provider. Systems can strengthen the established identity of the user by utilizing a revocable biometric for generating the biometric template that reflects changes in the user due to age or activity. In some embodiments, biometric data provided by a user during authentication can be matched with the dynamic biometric template to verify the identity of the user.

FIG. 1 depicts an exemplary system according to an embodiment of the invention.

Embodiments of the invention can include an authentication process utilizing a server implemented biometric authentication system with a generated biometric template from social media content of a user, comprising a number of components and in accordance with some embodiments of the invention. The process 100 illustrated in FIG. 1 includes a user 102 utilizing an access device 104 to submit biometric data 106 as part of an authentication request 108 to verify the user 102 or the access device 104. For example, the authentication request 108 may be part of a payment transaction for a payment process. As depicted in FIG. 1, the user 102 submits the biometric data 106 (a picture of the user's face) to service provider computers 112. In some embodiments, the service provider computers 112 implement or provide resources for implementing the features for biometric authentication as described herein. In other embodiments, the service provider computers 112 may be associated with an issuer of a payment instrument, a payment processing network associated with the payment instrument, a trusted third party, a digital wallet provider, a token requestor, and/or any other suitable entity. In some embodiments, the user 102 may utilize components, software, or hardware capabilities of the access device 104 to submit the biometric data 106 for authorization. For example, in FIG. 1, the user 102 may utilize a camera of the access device 104 to take a selfie or picture of themselves to submit with the authentication request 108.

Previously, the user 102 may have utilized a user device 114 to provide a digital video 116 (or one or more pictures) of themselves to a social network server computer 118 via the network 110. The submission of social media content (such as digital video 116) to the social network server computer 118 may have occurred previously, subsequently, concurrently, or asynchronously with the authentication request 108 by the user. In some embodiments, the social network server computer 118 may store the social media content (i.e., digital video 116) provided by the user 102 or associated with the user 102 in a social media content database 120. It should be noted that although FIG. 1 illustrates the user utilizing an access device 104 to make an authentication request 108 and a user device 114 to submit, share, or provide social media content, embodiments described herein include the user 102 utilizing either device (104 or 114) to both submit social media content and the authentication request 108. In some embodiments, the social network server computers 118 may provide, host, or maintain a social media Web Site or software application that the user 102 utilizes to submit, provide, or share social media content. The social network server computers 118 may maintain and update the social media content for each user of a plurality of users that share content utilizing their social media provided service in the social media content database 120.

In some embodiments, the service provider computer 112 may authenticate or verify the identity of the user 102 in response to receiving the authentication request 108. The service provider computer 112 may request, receive, or obtain the social media content (i.e., digital video 116) provided by the user 102 from the social network server computers 118 via network 110. In some embodiments, the service provider computer 112 may receive the social media content associated with the user 102 from the social network server computer 118 by invoking an application program interface (API) call that is provided by the social network server computer 118 to share such information with entities such as service provider computer 112. In some embodiments, the service provider computer 112 and social network server computer 118 may perform some form of authentication to ensure that sensitive data is not provided to unwanted parties. Further, the service provider computer 112 and social network server computer 118 may communicate the requested data via encrypted communications utilizing public-private encryption key pairs shared between the service provider computer 112 and social network server computer 118.

In some embodiments, the service provider computer 112 may utilize the social media content associated with the user 102 to generate a dynamic biometric template 122 for comparison to the submitted biometric data 106. In some embodiments, the service provider computer 112 may calculate a confidence score that represents the similarity or degree of matching between the biometric data 106 and the dynamic biometric template 122. The use of the dynamic biometric template 122 accounts for revocable biometric features of the user 102 (such as facial image data or voice data of the user 102). The use of revocable modalities may benefit the user in ensuring a greater degree of verification and authentication as revocable modalities such as facial image recognition are strengthened as a user's face changes over time. Moreover, a stronger dynamic biometric template 122 may be generated based on the amount of social media content associated with the user and can account for variations in how the biometric content was captured (i.e., lighting conditions and facial expressions). The service provider computer 112 may maintain the dynamic biometric template 122 and continually update (e.g., daily, each time a new image or video is provided, monthly, etc.) the dynamic biometric template 122 based on new or updated social media content received from the social network server computer 118. The dynamic biometric template 122 may be updated periodically by the service provider computer 112.

In some embodiments, the service provider computer 112 may determine an authentication response 124 based on the confidence score and a threshold. For example, the service provider computer 112 may maintain one or more thresholds for an authentication request based on characteristics of the authentication request or a payment transaction. A first threshold may be utilized based on information identifying the location of the user 102 or the access device 104 requesting authentication 108. A second threshold may be utilized for payment transactions that exceed or fall below a certain monetary amount. Other examples of thresholds are described herein. In embodiments, the authentication response 124 may indicate that the user's 102 identity or access device 104 is verified. In some embodiments, the authentication response 124 may be utilized as part of an authentication request message and authentication response message payment processing or payment transaction process. In some embodiments, the service provider computer 112 may generate a fraud score based on the comparison of the confidence score and the threshold. The fraud score may represent when authentication requests were verified or not verified. The fraud scores for a plurality of user's authentication requests may be tracked by the service provider computer 112 and be continually updated based on new authentication requests. In some embodiments, the service provider computer 112 may take one or more actions based on the fraud score such as informing merchants, issuer, and users of potential fraud.

In some embodiments, as described herein, the social network server computer 118 may generate and maintain the dynamic biometric template 122, perform the comparison of the biometric data 106 and the dynamic biometric template 122, and calculate the confidence score for subsequent provisioning to the service provider computer 112. In some embodiments, the access device 104 or user device 114 may be configured to utilize an application provided by the service provider computer 112 to generate and maintain the dynamic biometric template 122, perform the comparison of the biometric data 106 and the dynamic biometric template 122, and calculate the confidence score. The network 110 may include a wireless network, WI-FI, Wi-Max, wireless data network (e.g., 3G, 4G, or similar networks), or any other communication medium that may provide access to a public or private network.

FIG. 2 depicts a block diagram of a user device computer 200, in accordance with some embodiments of the invention. The user device computer 200 includes an input/output interface 202, memory 204, a processor 206, and computer readable medium 208. The user device computer 200 may be an example of access device 104 from FIG. 1.

The input/output (I/O) interface 202 is configured to receive and transmit data. For example, the I/O interface 202 may receive the user submitted biometric data 106 from the access device 104 (FIG. 1) or user submitted social media content for sharing with the social network server computer 118 (FIG. 1). In another example, the I/O interface 202 may transmit the biometric data 106 to the service provider computer 112 (FIG. 1) or the social network server computer 118 (FIG. 1). The I/O interface 202 may also be used for direct interaction with the service provider computer 112 or social network server computer 118. The I/O interface 202 may accept input from an input device such as, but not limited to, a keyboard, keypad, camera, microphone, mouse, or any other suitable input hardware and/or software associated with the user device computer 200 for capturing biometric data. Further, the I/O interface may display output on a display device.

Memory 204 may be any magnetic, electronic, or optical memory. It can be appreciated that memory 204 may include any number of memory modules. An example of memory 204 may be dynamic random access memory (DRAM).

Processor 206 may be any general-purpose processor operable to carry out instructions on the user device computer 200. The processor 206 is coupled to other units of the user device computer 200 including input/output interface 202, memory 204, and computer-readable medium 208.

Computer-readable medium 208 may be any magnetic, electronic, optical, or other computer-readable storage medium. Computer-readable storage medium 208 includes service provider module 210, authentication module 212, and social media network module 214.

The service provider module 210 may be configured to, when executed by processor 206, generate a dynamic biometric template utilizing social media content associated with a user, calculate a confidence score based on the comparison of submitted biometric data to the dynamic biometric template, and generate an authentication request to verify the identity of the user or the user device computer 200. After receiving the authentication request, the service provider module 210 may obtain and process the biometric data provided by the user requesting authentication. The service provider module 210 may then calculate the confidence score for the comparison of the biometric data to the generated dynamic biometric template. The service provider module 210 may facilitate the various transmitting and receiving of data by interfacing with I/O interface 202. In some embodiments, the service provider module 210 may generate and maintain the dynamic biometric template in an offline mode or depending on network conditions of the user device computer 200. For example, content received by the social media network module 214 may be utilized to update and/or generate the dynamic biometric template when the user device computer 200 is not connected to an available network (offline mode) or periodically as described above ing FIG. 1.

The social media network module 214 may be configured to, when executed by processor 206, request, receive, or obtain social media content from a social media network server or social media provider computer. The social media content may be provided or associated with the user of the authentication request. The social media network module 214 may generate the dynamic biometric template based at least in part on the social media content. The type of dynamic biometric template generated and stored may be based on the biometric data submitted by the user via the service provider module 210 during the authentication request process. The social media network module 214 may store the biometric template in memory 204 or in the computer-readable storage medium 208 in a protected sector that is only accessible by the social media network module 214. The social media network module 214 may maintain and update the biometric template based on new social media content provided or shared by the user with the social media network. In embodiments, the biometric template may be stored in a secure element of the user device. Secure elements may include a component of the user device or associated components that have been certified by the authentication service provider described herein as secure. The service provider may hold root access to the secure element and manage the secure element's lifecycle including creating security domains and sharing access keys with issuers.

The authentication module 212 may be configured to, when executed by processor 206, generate an authentication response or verify the authentication request based on the confidence score calculated by the service provider module 210 and one or more thresholds. The authentication module 212 may maintain a plurality of thresholds for authenticating an authentication request on behalf of a user or user device. In some embodiments, the authentication module 212 may be configured to select an appropriate threshold for authentication purposes. The authentication module 212 may utilize location information identified in the social media content from the social media network module 214 to select an appropriate threshold for comparison to the calculated confidence score. For example, a user may have interacted with a social network application to provide input about a merchant at a particular location. Subsequently an authentication request associated with the same merchant or merchant location may be processed by the modules 210-214.

The social media activity of the user for the merchant and the merchant location may be utilized to select a higher or lower threshold where appropriate to determine authentication. In embodiments where the authentication request is part of a payment transaction processing, the authentication module 212 may select a particular threshold based on the monetary amount for the transaction. For example, a higher threshold may be selected for a large monetary transaction (>$300.00) whereas a lower threshold may be selected for a small monetary transaction (<$50.00). In some embodiments, when a user registers or opts-in for the service described herein, utilizing biometric authentication with a dynamically generated biometric template from social media content, the user can set preferences for the monetary amount and thresholds described herein. In some embodiments, the authentication module 212 may generate a request for a secondary authentication from the user, beyond submitting biometric data. For example, for certain authentication requests or payment transaction processes, the authentication module 212 may request that the user submit a password, PIN, or answer a security question.

In some embodiments, the payment device 720 may be a plastic card linked to a user account.

The access device 730 may be an access point to a transaction processing system that may comprise the acquirer computer 730, the payment processing network computer 740, and the issuer computer 750. In some implementations, the access device 730 may be associated with or operated by the merchant computer 735. For example, the access device 730 may be a point of sale device that may include a contactless reader, an electronic cash register, a display device, etc. In some implementations, the access device 730 may be configured to transmit information pertaining to one or more purchased items at a merchant 735 to an acquirer 730 or payment processing network 740. In some implementations, the access device 730 may be a personal computer that may be used by the user to initiate a transaction with the merchant computer 735 (e.g., an online transaction). In some implementations, the access device may be configured to interface with a biometric reader to obtain biometric data pertaining to a biometric sample provided by a user.

The acquirer computer 730 may be operated by an acquirer. The acquirer is typically a system for an entity (e.g., a bank) that has a business relationship with a particular merchant, a wallet provider or another entity. The acquirer computer 730 may be communicatively coupled to the merchant computer 735 and the payment processing network 740 and may issue and manage a financial account for the merchant. The acquirer computer 730 may be configured to route the authorization request for a transaction to the issuer computer 750 via the payment processing network computer 740 and route an authorization response received via the payment processing network computer 740 to the merchant computer 735.

The payment processing network computer 740 may be configured to provide authorization services, and clearing and settlement services for payment transactions. The payment processing network computer 740 may include data processing subsystems, wired or wireless networks, including the internet. An example of the payment processing network computer 740 includes VisaNet™, operated by Visa®. Payment processing networks such as VisaNet™ are able to process credit card transactions, debit card transactions, and other types of commercial transactions. VisaNet™, in particular includes a Visa Integrated Payments (VIP) system which processes authorization requests and a Base II system which performs clearing and settlement services. The payment processing network computer 740 may include a server computer. In some implementations, the payment processing network computer 740 may forward an authorization request received from the acquirer computer 730 to the issuer computer 750 via a communication channel. The payment processing network computer 740 may further forward an authorization response message received from the issuer computer 750 to the acquirer computer 730. In some implementations, the payment processing network 740 may operate the service provider computer 112 (FIG. 1) or provide a software application configured to run on the access device 104, user device 114 (FIG. 1), or modules 210-214 of user device computer 200 (FIG. 2).

The issuer computer 750 may represent an account issuer and/or an issuer processor. Typically, the issuer computer 750 may be associated with a business entity (e.g., a bank) that may have issued an account and/or payment card (e.g., credit account, debit account, etc.) for payment transactions. In some implementations, the business entity (bank) associated with the issuer computer 750 may also function as an acquirer (e.g., the acquirer computer 730).

The issuer computer 750 and/or the payment processing network computer 740 may operate as authorization systems in some embodiments of the invention. For example, a transaction may be authorized by the issuer computer 750 and/or the payment processing network computer 740 upon successful biometric authentication by the user utilizing the dynamically generated biometric template derived from social media content associated with the user and biometric data provided by the user as disclosed herein.

The various entities in the system 700 may communicate with each other via an interconnected network 760, e.g., the Internet.

In some embodiments, the access device 730 may include or have a biometric reader coupled to it. After the payment device 720 intercts with the access device 730, the access device 730 may receive a biometric sample from the user as described above, and the user may be authenticated before the user is allowed to proceed with a payment transaction. Alternatively or additionally, the payment device 720 could request user authentication as described above, and could receive a confidence score as described above. Once the user is verified, the access device 730 may generate or obtain a confidence score from a remote computer or from the payment device, and may then generate an authorization request message which may pass to the issuer 750 via the acquirer 730 and the payment processing network 740. In some embodiments, the issuer 750, acquirer 730 and/or the payment processing network 750 could receive the confidence score and could decline the transaction if the confidence score is not satisfactory. The issuer 750 may then authorize the transaction, and may return an authorization response message back to the access device 730 via the payment processing network 740 and the acquirer 730. At the end of the day or any other suitable time period, a clearing and settlement process may take place.

In some embodiments, a user device computer 200 (FIG. 2) may be utilized to submit the biometric sample or biometric data from the user to begin the authorization and verification of the user identity prior to the generation of an authorization request message. In some embodiments, the user device computer 200 (FIG. 2) may provide the biometric sample or biometric data from the user to the access device 730 which is then subsequently provided to the payment processing network 740 for verification by utilizing the dynamically generated biometric template derived from social media content associated with the user.

The various participants and elements described herein with reference to FIGS. 1-6 may operate one or more computer apparatuses to facilitate the functions described herein. Any of the elements in FIGS. 1-6, including any servers or databases, may use any suitable number of subsystems to facilitate the functions described herein.

Examples of such subsystems or components are shown in FIG. 8. The subsystems shown in FIG. 8 are interconnected via a system bus 802. Additional subsystems such as a printer 804, keyboard 806, fixed disk 808 (or other memory comprising computer readable media), monitor 810, which is coupled to display adapter 812, and others are shown. Peripherals and input/output (I/O) devices, which couple to I/O controller 814 (which can be a processor or other suitable controller), can be connected to the computer system by any number of means known in the art, such as serial port 816. For example, serial port 816 or external interface 818 can be used to connect the computer apparatus to a wide area network such as the Internet, a mouse input device, or a scanner. The interconnection via system bus allows the central processor 820 to communicate with each subsystem and to control the execution of instructions from system memory 822 or the fixed disk 808, as well as the exchange of information between subsystems. The system memory 822 and/or the fixed disk 808 may embody a computer readable medium.

Embodiments of the invention have a number of advantages. For example, because a biometric template can be continually updated with social media images (e.g., photos, videos) a very up to date biometric template of a user may be maintained. This up to date biometric template may be used to authenticate a user for any suitable type of transaction including a payment transaction, an access transaction (e.g., to enter a venue or location), or a transaction to obtain a resource (e.g., a document or access to data). Further, because data from a social network is being leveraged, embodiments of the invention do not require significant changes to existing systems so that embodiments of the invention can be implemented without difficulty.

Any of the software components or functions described in this application, may be implemented as software code to be executed by a processor using any suitable computer language such as, for example, Java, C++ or Perl using, for example, conventional or object-oriented techniques. The software code may be stored as a series of instructions, or commands on a computer readable medium, such as a random access memory (RAM), a read only memory (ROM), a magnetic medium such as a hard-drive or a floppy disk, or an optical medium such as a CD-ROM. Any such computer readable medium may reside on or within a single computational apparatus, and may be present on or within different computational apparatuses within a system or network.

The above description is illustrative and is not restrictive. Many variations of the invention will become apparent to those skilled in the art upon review of the disclosure. The scope of the invention should, therefore, be determined not with reference to the above description, but instead should be determined with reference to the pending claims along with their full scope or equivalents.

One or more features from any embodiment may be combined with one or more features of any other embodiment without departing from the scope of the invention.

A recitation of “a”, “an” or “the” is intended to mean “one or more” unless specifically indicated to the contrary.
